Visualizing complex data can be challenging, especially when it comes to explaining complex systems. Graphs, tables, and charts can be powerful tools, but they can also be difficult to interpret. That’s where Sankey charts come in. These charts, based on the principle of flow diagrams, are ideal for visualizing complex data that involves two or more paths or elements.
Creating Your First Sankey Chart
Before you start creating a Sankey chart, you’ll need to gather your data. Sankey charts are typically used for visualizing two types of data: flow and activity flow. For flow, you’ll have separate paths for each item, with each path having different origins and destinations. For activity flow, you’ll have a network of nodes and arcs connecting each node to the next.
Once you have your data ready, it’s time to create your Sankey chart. Begin by laying out your nodes and arcs. Start with the biggest node (or first node) and add the first arc, connecting it to the next node. Then, repeat this process, adding each subsequent arc in the order of its location. Each arc should have a label that is related to the activity or flow it represents.
Once you have created your Sankey chart, you’ll need to interpret it. Look for patterns and flow patterns. For example, you may find that certain nodes (or arcs) connect frequently, indicating higher activity or flow. You may also notice that certain areas have higher activity or flow than others, indicating areas of greater complexity or variation.
Applications of Sankey Charts
Sankey charts are particularly useful for visualizing complex data and systems. They can be used in a variety of fields, including business, finance, public health, and the military. Here are some examples of how Sankey charts can be used:
- Business: In business and finance, Sankey charts can be used to explain the flow of capital (such as investment, loans, and revenue streams) between different departments or segments of a business.
- Public Health: In health research and analysis, Sankey charts can be used to visualize the flow of information (such as data on diseases, treatments, and research progress) between different sources and destinations.
- Military: In the military, Sankey charts can be used to visualize the flow of resources between different areas of operations or units.
Creating Your First Sankey Chart
If you’re ready to start creating your own Sankey chart, here’s how to get started:
- Gather your data: Collect the data you need for your Sankey chart. Make sure to include all the information you’ll need for the arcs to connect correctly.
- Create your nodes and arcs: Lay out your nodes (or initial arcs) and arcs. Start with the biggest node and connect it to the first arc. Then, create the next arcs, connecting them to the next nodes.
- Interpret the chart: Look for patterns and flow patterns in your Sankey chart. High activity or flow in some areas indicates areas of greater complexity, while areas with lower activity or flow may indicate areas of variation.
- Use your Sankey chart: Once you’ve created your chart, you can use it to explain complex systems and explain data flows. Explore the chart, interpreting its underlying patterns and flows, to gain a deeper understanding of your data.
